Nitrous Express Stand Alone Fuel Enrichment System
Features: 3-Quart Composite Fuel Cell; External Low-Pressure Pump; Non-Bypass Style Regulator (5-12 PSI). Best for drivers needing a compact, self-contained enrichment system with an external pump. Suitable for street and track use where a modest horsepower increase is desired. This setup suits nitrous users who prioritize simplicity and compact packaging.
Best for: Street cars and light-track applications needing reliable fuel enrichment with a small tank. Choose this if you want a straightforward, integrated system with adjustable pressure and external pumping.
Caution: The external pump and regulator must be correctly mounted and wired to avoid fuel delivery issues at high nitrous flow. Ensure compatible fittings and safety wiring for ignition-off scenarios.
Nitrous Outlet Dedicated Fuel System Dual Fuel Supply Plumbing Kit
Features: Dual fuel supply plumbing with black fittings for a clean install. This kit is designed to support dedicated fuel routing for nitrous systems, enabling more complex or higher-output configurations. Best for: builds requiring robust plumbing with a clean, stealthy appearance.
Best for: Enthusiasts who want a durable, professional-grade plumbing solution to support higher nitrous duty cycles. Avoid this if you need a simple, single-line setup.
Caution: Proper routing and secure fittings are essential to prevent leaks under high pressure. Verify compatibility with your fuel pump and nitrous solenoid arrangement.
Nitrous Express ML2000 50-150 WHP MainLine EFI System
Features: Universal EFI compatibility; White bottle with chrome valve; Stainless steel bottle brackets and solenoids. Best for: EFI-equipped engines that want a nitrous enrichment system integrated with modern EFI controls. This system is suitable for more advanced users who value compatibility with non–TBI EFI setups.
Best for: Vehicles using modern EFI without carburetion, aiming for a clean, integrated nitrous boost. Caution: Ensure EFI system controls can coordinate with nitrous activation to prevent lean conditions.
Nitrous Express 15004 Boosted Stand Alone Fuel Enrichment
Features: One gallon high-strength composite fuel cell; can mount in most factory battery trays; pump supports up to 700 hp at 5 psi and up to 500 hp at 45 psi on gasoline or race fuel; 550 hp on Methanol at 5 psi; pre-assembled with high-output internally mounted fuel pump and adjustable external regulator. Best for: High-horsepower nitrous builds that require a robust, standalone enrichment solution with strong HP capabilities.
Best for: Serious drag or street/strip setups needing substantial fuel delivery with a compact form factor. Caution: High HP claims assume proper tuning; verify compatibility with your fuel type and nitrous setup.
Nitrous Outlet Plastic Universal Fuel Tank/Vented Cap/Mounting Bracket
Features: Universal fuel tank with vented cap and mounting bracket. Best for: Replacement or upgrade projects requiring a flexible tank solution compatible with various nitrous setups. This kit supports secure mounting and venting for stable fuel supply.
Best for: Builders needing a compatible tank option to complete a standalone fuel enrichment system. Caution: Verify capacity and mounting compatibility with your chassis and existing fuel lines.
Buying Guide: Key Considerations For Choosing A Nitrous Fuel System
- System type: Choose between a standalone enrichment system with its own tank and pump or a plumbing kit that integrates with an existing fuel system.
- Fuel capacity: Larger tanks provide longer runtime between fills but add weight and space considerations. Consider your racing or street usage pattern.
- HP target: Ensure the system supports your intended nitrous horsepower increase. Some units are optimized for 50-150 hp, others for 700 hp at low psi.
- Fuel compatibility: Verify compatibility with gasoline, race fuel, or methanol. Some systems perform differently across fuels.
- EFI integration: If your engine uses EFI, confirm EFI compatibility and how the nitrous system coordinates with fuel management to avoid lean conditions.
- Installation complexity: Some kits are pre-assembled and easier to install; others require more custom plumbing and wiring. Choose based on your skill level.
- Safety and regulatory: Ensure components meet safety standards and align with local regulations for nitrous use on vehicles.
- Maintenance: Consider pump reliability, regulator adjustability, and ease of service in the field.
Frequently Asked Questions
- What is a dedicated fuel system for nitrous used for?
– It provides stable fuel pressure and delivery specifically for nitrous, improving consistency and protecting the engine during nitrous use. - Do I need a standalone tank or can I use my existing fuel cell?
– A standalone tank is common for dedicated nitrous systems, offering clean separation and easier tuning. Some setups can piggyback on existing cells if properly configured. - What horsepower range should I target with these systems?
– Systems in this list range from modest gains to high-HP capability, depending on the pump, tank size, and regulator; match to your desired nitrous output and engine strength. - Is EFI compatibility important for nitrous systems?
– Yes, especially for modern engines; ensure the system coordinates with EFI controls to avoid lean conditions and ensure proper fueling. - What maintenance is required for a nitrous fuel system?
– Regular inspection of fittings, hoses, and electrical connections; monitor fuel pressure with the regulator and replace worn components as needed. - Can I install these myself?
– Installation depth varies; simpler kits are DIY-friendly, while others may require professional installation depending on vehicle wiring and fuel plumbing.
